That did the trick with the pstn line, thanks a lot.
Username entered in the spa3102 box, should be the peer-name and not the username as stated in the other guides.
However line1 does not work with the dial plan stated (*x.|*xx*|x.). When I leave the original it works (*xx|[3469]11|0|00|[2-9]xxxxxx|1xxx[2-9]xxxxxxS0|xxxxxxxxxxxx.)
